  • Another answer to the CAPTCHA problem?

    - by Xeoncross
    Most sites at least employ server access log checking and banning along with some kind of bot prevention measure like a CAPTCHA (those messed-up text images). The problem with CAPTCHAs is that they poss a threat to the user experience. Luckily they now come with user friendly features like refresh and audio versions. Anyway, like linux vs windows, it isn't worth the time of a spammer to customize and/or build a script to handle a custom CAPTCHA example that only pertains to one site. Therefore, I was wondering if there might be better ways to handle the whole CAPTCHA thing. In A Better CAPTCHA Peter Bromberg mentions that one way would be to convert the image to HTML and display it embedded in the page. On http://shiflett.org/ Chris simply asks users to type his name into an input. Examples like this are ways to simplifying the CAPTCHA experience while decreasing the value for spammers. Does anyone know of more good examples I could use or see any problem with the embedded image idea?

  • Drag Rotate UIImageView by touch

    - by rockstardev
    I have an UIImageView that is a subview of an UIView. I'm trying to create a drag rotate effect with the UIImageView similar to spinning a bottle but I'm having trouble calculating the radians to rotate the image by. My code below seems like it should work because I've seen a similar calculation in Flash examples. Can anyone shed some light on what I'm doing wrong? Thanks. This is the code contained in my image view subclass: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; lastLocation = [touch locationInView:[self superview]]; } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; CGPoint location = [touch locationInView:[self superview]]; CGFloat xDisplacement = location.x - lastLocation.x; CGFloat yDisplacement = location.y - lastLocation.y; CGFloat rad = atan2f(yDisplacement,xDisplacement); self.transform = CGAffineTransformMakeRotation(rad); }

  • Web development - relative URLs without duplicating files

    - by eshriek
    I have a site with index.php in the root folder, images in /img , and overview.php in /content . I have a sidebar.php file that is included in both index.php and overview.php . How should I refer to /img/image.gif if I include a link in each file? The location of image.gif changes relative to the location of the file that references it. Using /img/image.gif in sidebar.php will work in index.php, but it fails for the file located at /content/overview.php. The only solution that I can see is to either include a seperate sidebar.php in each subdirectory, or include an /img directory in every sub-directory. The best suggestion that I can find is to use the <base html tag as suggested here: Change relative link paths for included content in PHP However, in the same link, SamGoody suggests that the <base tag "is no longer properly supported in Internet Explorer, since version 7." I'd like some insight on the matter before committing to a course of action. Thanks. EDIT: I am using the wrong approach below with "../" Example- root/index.php: ... <link rel="stylesheet" type="text/css" href="style.css" /> <title>title</title> </head> <body> <?php include('include/header.php'); ?> <?php include('include/menu.php'); ?> ... root/include/header.php: ... <div id="header"> <span class="fl"><img src="img/dun1.png"/></span><span class="fr"><img src="img/dun2.png"/></span> ... root/content/overview.php: ... <link rel="stylesheet" type="text/css" href="../style.css" media="screen" /> <title>Overview</title> </head> <body> <?php include('../include/header.php'); ?> <?php include('../include/menu.php'); ?> ...

  • Show javascript execution progress

    - by Midhat
    I have some javascript functions that take about 1 to 3 seconds. (some loops or mooML templating code.) During this time, the browser is just frozen. I tried showing a "loading" animation (gif image) before starting the operation and hiding it afterwords. but it just doesnt work. The browser freezes before it could render the image and hides it immediately when the function ends. Is there anything I can do to tell the browser to update the screen before going into javascript execution., Something like Application.DoEvents or background worker threads. So any comments/suggestions about how to show javascript execution progress. My primary target browser is IE6, but should also work on all latest browsers

  • Will Google Analytics track URLs that just redirect?

    - by Derick Bailey
    I have a link on my site. That links goes to another URL on my site. The code on the server sees that resource being requested and redirects the browser to another website. Will Google Analytics be able to know that the user requested the URL from my server and was redirected? Specifically, I set up a /buy link on my watchmecode.net site to try and track who is clicking the "Buy & Download" button. This link/button hits my server, and my server immediately does a redirect to the PayPal processing so the user can buy the screencast. Is Google Analytics going to know that the user hit the /buy URL on my site, and track that for me? If not, what can I do to make that happen?

  • How do I get a Canon LBP5000 Printer working?

    - by Saigun
    I have unsuccessfully attempted to install a Canon LBP5000 printer on Ubuntu 11.10. I have attempted all possible methods to be found on the web, but nothing seems to work. My latest attempt was Radu Cotescu's script from http://radu.cotescu.com/how-to-install-canon-lbp-printers-in-ubuntu/ Using the script everything appears to work as described during the installation process, but when attempting to actually print, it remains stuck in “processing” (regardless of what I attempt to print) [There is no additional error message]. Could anyone help me? It would be very much appreciated!

  • Iphone UIButton not working in nested UIViews

    - by Charles Peterson
    This is so damn simple im sure! Im missing something and im exhausted from trying to fix it. hopefully someone can help. The Button in CharacterView.m works but the button nested down in CharacterMale.m does not. I'm not using IB everything is done progmatically. What would cause one button to work and other not? ///////////////////////////////////////////////////////////////////////////////// CharacterController.m ///////////////////////////////////////////////////////////////////////////////// #import "CharacterController.h" #import "CharacterView.h" @implementation CharacterController - (id)init { NSLog(@"CharacterController init"); self = [ super init ]; if (self != nil) { } return self; } - (void)loadView { [ super loadView ]; characterView = [ [ CharacterView alloc ] init]; self.view = characterView; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } - (void)dealloc { [super dealloc]; } @end ///////////////////////////////////////////////////////////////////////////////// CharacterView.m ///////////////////////////////////////////////////////////////////////////////// #import "CharacterView.h" #import "CharacterMale.h" @implementation CharacterView - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { characterMale = [ [ CharacterMale alloc ] init]; [self addSubview: characterMale]; UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(0, 200, 200, 100); [button setImage:[UIImage imageNamed:@"btnCharSelect.png"] forState:UIControlStateNormal]; [button addTarget:self action:@selector(ApplyImage:) forControlEvents:UIControlEventTouchUpInside]; [ self addSubview: button ]; } return self; } - (void)drawRect:(CGRect)rect { } -(void)ApplyImage:(id)sender { NSLog(@"CharacterView button works"); } - (void)dealloc { [super dealloc]; } @end ///////////////////////////////////////////////////////////////////////////////// CharacterMale.m ///////////////////////////////////////////////////////////////////////////////// #import "CharacterMale.h" #import "CharacterController.h" @implementation CharacterMale - (id)init { self = [ super init]; if (self != nil) { UIImage *image = [UIImage imageNamed:@"charMale.png"]; imageView = [[ UIImageView alloc] initWithImage:image]; [image release]; [ self addSubview: imageView ]; UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(0, 0, 200, 100); [button setImage:[UIImage imageNamed:@"btnCharSelect.png"] forState:UIControlStateNormal]; [button addTarget:self action:@selector(ApplyImage:) forControlEvents:UIControlEventTouchUpInside]; [ self addSubview: button ]; } return self; } -(void)ApplyImage:(id)sender { NSLog(@"CharacterMal button works"); } - (void)dealloc { [super dealloc]; } @end

  • Why must "stride" in the System.Drawing.Bitmap constructor be a multiple of 4?

    - by Gorchestopher H
    I am writing an application that requires me to take a proprietary bitmap format (an MVTec Halcon HImage) and convert it into a System.Drawing.Bitmap in C#. The only proprietary functions given to me to help me do this involve me writing to file, except for the use of a "get pointer" function. This function is great, it gives me a pointer to the pixel data, the width, the height, and the type of the image. My issue is that when I create my System.Drawing.Bitmap using the constructor: new System.Drawing.Bitmap(width, height, stride, format, scan) I need to specify a "stride" that is a multiple of 4. This may be a problem as I am unsure what size bitmap my function will be hit with. Supposing I end up with a bitmap that is 111x111 pixels, I have no way to run this function other than adding a bogus column to my image or subtracting 3 columns. Is there a way I can sneak around this limitation?

  • how to get the camera data

    - by beof
    Hello ,guys, My app needs to get the camera data from Iphone. In my ImagePickerController, there is overlayView drawing realtime indications. I use UIGetScreenImage() to get the screenshot, and I also dump overlayview to image, then I can restore the original Image based on these two images. if the overlayView is still, it works quite well, but if the overlayView keeps changing, UIGetScreenImage() can not keep up with it. For example,if the overlayView changes from a rectangle to a circle, then calling UIGetScreenImage() returns with a rectangle on top of it. Is there a way to get the realtime camera data? I really appreciate if someone could help.

  • Put an object in Handler message

    - by Tsimmi
    Hi! I need to download an image from the internet, in a different thread, and then send that image object in the handler message, to the UI thread. I already have this: ... Message msg = Message.obtain(); Bundle b = new Bundle(); b.putParcelable("MyObject", (Parcelable) object); msg.setData(b); handler.sendMessage(msg); And when I receive this message, I want to extract the object: ... public void handleMessage(Message msg) { super.handleMessage(msg); MyObject objectRcvd = (MyObject) msg.getData().getParcelable("IpTile"); addToCache(ipTile); mapView.invalidate(); } But this is giving me: ...java.lang.ClassCastException... Can anyone help? And by the way, is this the most efficient way to pass an object to the UI Thread? Thank you all!

  • Integrating a Progress Bar into a Wizard

    - by Geertjan
    Normally, when you create a wizard, as described here, and you have your own iterator, you'll have a class signature like this: public final class MyWizardWizardIterator implements WizardDescriptor.InstantiatingIterator<WizardDescriptor> { Let's now imagine that you've got some kind of long running process your wizard needs to perform. Maybe the wizard needs to connect to something, which could take some time. Start by adding a new dependency on the Progress API, which gives you the classes that access the NetBeans Platform's progress functionality. Now all we need to do is change the class signature very slightly: public final class MyWizardWizardIterator implements WizardDescriptor.ProgressInstantiatingIterator<WizardDescriptor> { Take a look at the part of the signature above that is highlighted. I.e., use WizardDescriptor.ProgressInstantiatingIterator instead of WizardDescriptor.InstantiatingIterator. Now you will need to implement a new instantiate method, one that receives a ProgressHandle. The other instantiate method, i.e., the one that already existed, should never be accessed anymore, and so you can add an assert to that effect: @Override public Set<?> instantiate() throws IOException {     throw new AssertionError("instantiate(ProgressHandle) " //NOI18N             + "should have been called"); //NOI18N } @Override public Set instantiate(ProgressHandle ph) throws IOException {     return Collections.emptySet(); } OK. Let's now add some code to make our progress bar work: @Override public Set instantiate(ProgressHandle ph) throws IOException {     ph.start();     ph.progress("Processing...");     try {         //Simulate some long process:         Thread.sleep(2500);     } catch (InterruptedException ex) {         Exceptions.printStackTrace(ex);     }     ph.finish();     return Collections.emptySet(); } And, maybe even more impressive, you can also do this: @Override public Set instantiate(ProgressHandle ph) throws IOException {     ph.start(1000);     ph.progress("Processing...");     try {         //Simulate some long process:         ph.progress("1/4 complete...", 250);         Thread.sleep(2500);         ph.progress("1/2 complete...", 500);         Thread.sleep(5000);         ph.progress("3/4 complete...", 750);         Thread.sleep(7500);         ph.progress("Complete...", 1000);         Thread.sleep(1000);     } catch (InterruptedException ex) {         Exceptions.printStackTrace(ex);     }     ph.finish();     return Collections.emptySet(); } The screenshots above show you what you should see when the Finish button is clicked in each case.

  • How to order the images in a mysql database?

    - by user305270
    Hy! Here is my problem: i have a profile and this profile has for example 100 images. When someone visit this profile the first image will be the first result of my query that sorts by updated_at. But if the user would want to put the image with the (id = 8) to be the first, then (id = 22) then (id = 88) and so on? I need to put another field or is really necessary a new table to make a custom sort on images? and maybe someone explain this to me how to do? thanks, i appreciate your help ;)

  • OpenGL behaviour depending on the graphics card?

    - by Dan
    This is something that never happened to me before. I have an OpenGL code that uses GLSL shaders to texture a 3D model. The code involves a lot of GPU texture processing, blending, etc... I wanted to check how the performance of my code improves using a faster graphics card (both new and old are NVIDIA, using always the NVIDIA development drivers). But now I have found that once I run the code using the new graphics card, it behaves completely different (the final render looks wrong), probably because some blending effect is not performed correctly. I haven't really look into what has changed, but I am guessing that some OpenGL states are, by default, set different. Is this possible? Have you ever found different OpenGL/GLSL behaviour using different graphics cards? Any "fast" solution? (So far I've thought of plugging back the old one, push all OpenGL default states, and compare with the ones I initially get using the new card..)

  • How to debug a server that crashes once in a few days?

    - by Nir
    One of my servers crashes once in a few days. It does low traffic static web serving + low trafic dynamic web serving (PHP, local MYSQL with small data, APC, MEMCACHE) + some background jobs like XML file processing. The only clue I have is that a few hours before the server dies it starts swapping (see screenshot http://awesomescreenshot.com/075xmd24 ) The server has a lot of free memory. Server details: Ubuntu 11.10 oneiric i386 scalarizr (0.7.185) python 2.7.2, chef 0.10.8, mysql 5.1.58, apache 2.2.20, php 5.3.6, memcached 1.4.7 Amazon EC2 (us-west-1) How can I detect the reason for the server crashes ? When it crashes its no longer accessible from the outside world.

  • Is there a way to add Google Docs-like comments to any web page?

    - by Sean
    You know the comments on Google Docs word processing documents? And how it creates a little discussion over in the right-hand margin? I love it. Great for collaboration. I want to free it from Google Docs so I can use it with clients to discuss mock-ups or scaffolded websites. Searching Google for "add comments [or discussions] to any website" only gets you results for adding blog-like comments (Disqus, JS-Kit, etc.) Anyone know of a solution for what I'm after here?

  • Rmagick Fails To Manipulate PNG

    - by Tyler DeWitt
    Following the Railscast episode on CarrierWave: I installed ImageMagick on Mountain Lion via homebrew, exported the following path: export PKG_CONFIG_PATH="/opt/local/lib/pkgconfig:$PKG_CONFIG_PATH" Symlinked the following: ln -s /usr/local/include/ImageMagick/wand /usr/local/include/wand ln -s /usr/local/include/ImageMagick/magick /usr/local/include/magick And installed rmagick via bundler. In my uploader I have the following: include CarrierWave::RMagick version :thumb do process :resize_to_limit => [85, 85] end Which creates thumbnails just fine, but not for png files. I've tried a handful of png images and it always fails with this error: Failed to manipulate with rmagick, maybe it is not an image? Original Error: no decode delegate for this image format `<path>/public/uploads/tmp/20121022-2133-9885-3333/thumb_cat_vs_internet.png' @ error/constitute.c/ReadImage/544 jpeg images work just fine. EDIT identify -list format | grep -i png returns nothing, indicating the png decode delegate is probably missing. Now what?

  • DataSets and XML - The Simplistic Approach

    One of the first ways I learned how to read xml data from external data sources was by using a DataSet’s ReadXML function. This function takes file path for an XML document and then converts it to a Dataset. This functionality is great when you need a simple way to process an XML document.  In addition the DataSet object also offers a simple way to save data in an xml format by using the WriteXML function. This function saves the current data in the DataSet to an XML file to be used later. DataSet ds  = New DataSet();String filePath = “http://www.yourdomain.com/someData.xml”;String fileSavePath = “C:\Temp\Test.xml”//Read file for this locationds.readxml(filePath);//Save file to this locationds.writexml(fileSavePath); I have used the ReadXML function before when consuming data from external Rss feeds to display on one of my sites.  It allows me to quickly pull in data from external sites with little to no processing. Example site: MyCreditTech.com

  • Simultaneously execute two queries on a shell script

    - by Alex
    I have a shell script in which I have to execute two queries (on different databases), spool their results to text files and finally call a c++ program that processes the information on those text files. Something like this: sqlplus user1/pw1@database1 @query1.sql sqlplus user2/pw2@database2 @query2.sql ./process_db_output Both queries take some time to execute. One of them can take up to 10 minutes, while the other one is usually faster. What I want to do is execute them simultaneously and when both are done, call the processing utility. Any suggestion on how to do so?

  • iPhoneOS SDK - Remove Corner Rounding from views (iPad problem)

    - by norskben
    Hi Guys This might be a little bit picky, but in the iPad SplitViewController setup, there are 2 views. Each of the views has a very small black corner rounding. (This is probably the same with iPhone apps too). This rounding is visible in the image below. What I would like to do is remove the black rounding, so the UI doesnt get these two little bumps along the bottom. Has anyone done this, or know how to? -Its surely possible. Hopefully some one has seen this before. Thanks Image Link Mirror

  • RTOS experience

    - by Subbu
    Hi, I have been working as an embedded software engineer on mostly 8 bit micro-controller firmware and desktop/mobile applications development for the past five years. My work on a WinCE project (in which I got introduced to .NET CF) was short lived. I did use core APIs for interrupt processing, peripheral communication, etc...but again, not exactly a pure RTOS environment. In order to get together more solid experience for growing more in the embedded field, I want to work more with RTOSes. Will buying an evaluation board with an RTOS and putting together a project at home be regarded as a good experience or will an online course be more useful? I am just not clear as to what will be regarded as good experience. Any suggestions or directions will greatly help me. I have a passion for the field but just a need a point in the right direction. Thanks for any help in advance. Regards, Subbu
